The TVS-1004 and TVS-1008
automatic temperature and velocity
scanners are portable, 4- and
8-channel hot wire anemometer
systems. The TVS-1100 series are
factory expandable for up to 32 total
sensors. Fully automated, these
research-quality instruments take
accurate single- or multi-point
measurements of air temperature,
velocity and surface temperature in
complex environments, such as
PCBs and electronics enclosures.
When used as temperature loggers,
they can measure both fluid and
solid temperatures.

The TVS-1000 series employ
patented, fast response, omnidirectional
sensors, which measure
both temperature and velocity. This
patented single-sensor technology
eliminates errors introduced as a
result of air flow being non-isothermal.
Each precisely calibrated sensor is
flexible and robust with a low-profile
configuration that allows minimally
intrusive mounting throughout the
peaks and valleys created by the PCB components. These
systems require a PC to
operate and utilize the
provided software for
data acquisition and
reporting.

The candlestick style
sensor, is a flexible,
robust, base-and-stem
design sensor that measures both
temperature and air velocity for
characterizing thermal conditions in
electronic systems. The candlestick
sensor is narrow and low profile to
minimize the disturbance of the
heat flow in the test domain. It
features a flexible, plastic-sleeved
stem, which facilitates installation
and repositioning during the testing
process. Sensors are calibrated for
low (natural convection) and high
velocity flows. They are capable of
temperature measurements ranging
from -30 to 150°C ±1°C. Velocity
measurements range from 0 to 20 m/s (4,000 ft/min).
Higher ranges available, contact Omega for details.
The use of a single sensor to measure both
temperature and velocity eliminates
errors that can occur when airflow
is non-isothermal. Multiple
candlestick sensors can be easily
installed to thoroughly map a
system’s thermal and airflow
conditions. Their robust nature
allows for continuous repositioning
and reading.
